Which parsley herb will grow taller, Light or
Dark?
We think that the plant that is in the light will
grow taller because the plant needs sunlight to
go through photosynthesis.
We will be covering the question and facts about
the herb. And what the effects of light and dark
can be on the plant.

 The
scientific
name for parsley
is: Petroselinum
crispum
 Photosynthesis
releases oxygen
from the plant

The
function of Apiol and Myristican is to be
an insecticide.
 The function of an insecticide is to repel
predators
This organic compound is an adaptation,
because it helps it survive.
Common uses for this herb are food, and
medicines.
The Romans were the first to use parsley
 They used it for flavoring for food. Then
Parsley spread to America in the 17th century.
 Now it is the most used culinary herb
worldwide
Parsley Is used in medicines to calm spasms
and other things that harm your nervous
system. It is also used in insecticide and
cooking.
The function of photosynthesis
is to create sugar, the plants
food, for the plant.
The chemical reaction that
occurs is that water, sunlight,
and carbon dioxide reacts to
each other to create sugar for
the plants.
The chloroplasts are the
organelle that are responsible
for causing
•Sunlight
is a factor in a plants growth because it
let the plant go into photosynthesis and produce
food and without food they cannot grow.
•Water because of the fact that water is a main
ingredient in photosynthesis and without it like
sunlight the plant cannot grow.
• And last but not least is carbon dioxide, a plant’s
oxygen and also something that’s required to go
through photosynthesis.
We first choose our seeds.
 Then we planted our seeds in the cups of mulch.
 Then we put the plants in under light or dark.
 Then we watered the plants.
 Then we decided who would water the plants.
 Then we watered each day and recorded their
height each day.

 Our
plant that actually was in the light grew up
and our plant that was in the dark dropped a
little. So our light plant was showing positive
tropisms and our dark plant was showing
negative tropisms.
 Both of the plants roots grew into the soil, this
process is called positive geotropisms.
 The most unusual thing was that our plant in
the dark stem turned clear.
Our results concluded that the plant in the
light would last longer and grow faster also
would grow taller.
 The results did support our hypothesis being
that the plant in the light grew faster and
taller.
 One thing that our group thought of that
could make the investigation better was,
having someone monitor the plants and
measure them over the weekends, and days
that we don’t have science.

 Where
we got most of our information is
from the website:
 http://m7science.wikispaces.com/
 We also got help from Mr. Martell and from
our journals for some of our information.
